Todd Bradley is stepping down in May as chief executive officer of PalmOne, maker of the Palm OS mobile operating system.
Company president Ed Colligan will become interim CEO while a search is conducted for Bradley's permanent replacement. Colligan is a candidate for the permanent position, said PalmOne.
"I've accomplished what I set out to do," Bradley said. "The company is on a growth path. I feel the time is right for me to move on to another challenge."
Colligan was previously the chief operating officer of Handspring, an innovative handheld supplier which palmOne acquired under Bradley’s leadership.
Eric Benhamou, palmOne chairman, said, "Todd has accomplished his mission, and we thank him for the contributions he made in steady financial improvements, in bringing innovation to the product roadmap and in pursuing the right strategic objectives, including the acquisition of Handspring."
